To all whom it may concern Be it known that I I-LmRIsoN M. BRIGHT MAN, a citizen of the United States of America, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements ,in Nut-Castellating Machines, of which the following is a specification.

My present invention relates to improvements 1n nut castellatmg machines, and 1s its-connections where y the cutter or cutters may be adjusted. with relation to the work and whereby the work may be held by an adjustable and adaptable device for the purpose, and 1n further combinations of parts to be pointed out in the claims appended heieto.

In the accompanying illustrated one complete example of the physical embodiment of my invention constructed according to the best mode I have so far devised for the application of the principles of my invention.

Figure 1 is a side elevation of a nut castellating machine constructed according to' my invention. :Fig. 2 is an end elevation of Fig. 1, at -the right. Fig. 3 is a sectional view of part of the machine on line A--A Fig. 1. Fig. 4 is a longitudinal detail sectional view of part of the drum or carrier for the nuts, Fig. 5 is an enlarged detail of drum showing a nut in a pocket or socket of the drum or carrier. Fig. 6 is a perspective view of a nut having one groove out in it from the machine.

In the preferred embodiment of my invention as illustrated in the drawings, the machine is supported upon a table 1 of usual or suitable size, is fixed to the table, as a-support for the operating parts of the machine. 7

The drum 3 is a rotary carrier designed to carry the nuts which are being castellated drawings I have and the bed 2 of the machine 7 and is supported upon a shaft 4 journaled in the posts or uprights 5 5 rising fromv the bed 2 ,ofgthe machine. The carrier comprises a metallic pulley or Wheel 6 having attached thereto in close relationship a series of rings or bands 7 of which. the end rings arepromded with notches at their inner sides and the intermediate rings are fashioned with notches at both sides in order to .form diamond-shaped pockets on sockets 8 8 in which the nuts 9 are to be carried. The notches are cut in the rings with uni- I formity'so that adjoining bands will through their notches, register and form the pockets, but the rings are spaced apart the width of a groove 10 in the periphery of the drum,

.and the rings are secured to the drum by pins, screws, etc. as indicated at 11.. I have illustrated six series of pockets in Fig. 1 of the drawings, but it will be understood that this number may be increased or diminished to suit circumstances. The

carrier is trotated or revolved through the instrumentality of a worm wheel 12 on the shaft 4, a worm 13 on the worm shaft 14, a second worm wheel 15 on the shaft 14 and a second worm 16 on the driving shaft 17 which may be rotated by the pulleys 18, the dlrection of rotation being indicated by the arrow in Figs. 1, 2 and 3.'

a Each series of nuts to be castellated is held in place by an adjustable presser foot 19 which is flexibly supported between the upper and lower flanges 20 and 21 of a hous ing 22, and each foot is provided with a pair of guide bars as 23, 23, passed through openings in lugs 24, 24 integral with the housing, and between these lugs and the adjustable nuts 25 on the guide bars a spring 26 is interposed causing the foot 19 to press on the nuts as they pass around carried by the carrier. The foot is curved of course to conform to the periphery of the carrier and it is sufi'iciently flexible to permit it to adjust'itself to any irregularities in the nuts, or to. nuts which might not be resting in their pockets with firmness. However, the presser foot holds the nuts firmly in position while they'are being grooved or castellated by means of one of the cutters indicated at 27. The presser foot -.is pivoted at 28 to the guide bars 23, and the movement of the presser foot is restricted and guided by the two flanges 20 and 21 of the housing 22. One rotary cutter 27 is provided for each series of nut pockets and these cutters each project through a slot indicated by dotted lines at 29 Fig. 3, in position to cut a groove in the nuts as indicated in Fig. 6. The cutters are arranged transversely of the carrier on a shaft 30 supported in parallel position with relation to the shaft of the carrier, ll slidable journal bearing blocks 31, 32 32. .The block 31 is mortised or grooved so that it will slide over the tenon 31 of the upright 33, and the two blocks 32 slide on the posts 34 34 when the screw bars 35 are turned. These bars support blocks 32and uppr screw bars 35" hold themin adjusted position. When the master gear 36 located beneath the machine, is turned it also turns the two smaller gears 37 37'1fixed on the lower ends of the screw bars 35, to raise or lower the blocks 32 and with them the shaft 30 journaled therein. The cutter shaft is driven-from a driving shaft 38 through a pinion 39 on this shaft and a gear 40 on the cutter shaft, and the driving shaft is rotated by using the pulleys 41 or 41 (see Fig. 1). The housing 22 whichsupports the presser foot is also adjustably supported, but independent of the cutters, and is formed with a pair of slots 42 42 through which pass the bolts 43 to secure it to the upright 34.

fter the nuts have been grooved or castellated they are ejected from the carrier by means of a pivoted pawl 44 tion to have its flattened end lie in the groove 10 in the drum in order that it will bear lightly upon the drum and eject the oncoming nuts as seen in Fig. 3. The movement of the pawl is regulated by means of the set screw 45, which is threaded through the arm 46 of the pawl, and has its end resting ,i htly upon the top of the bed of the machlne.

The nuts are placed in their pockets by hand, at the top of the carrier and are positioned as indicated in Fig. 5. As the car rier turns clockwise as indicated by the arrows the nuts are brought, three or four at a time, under the presser foot which holds them during the cutting operation. The carrier is turning clockwise, and it will be noted that the cutter is also turning in that direction so that the tendency of the cutter is to force the nut up against the upper walls of the pocket and it is held rigidly and firmly in this position during the cutting operation. After the cutter has grooved the nut, or its crown, as indicated in Fig. 6, it passes out from beneath the presser fodt; and if it does not fall out by gravity, it is ejected by the sharpened pawl 44. The nut falls into a which is in POSlrated lugs on the housing,

notched edges to araeoc receptacle, is again picked up, and again placed in a pocket, to be grooved a second, and then again a third time. The pockets are purposely made somewhat larger than the nuts so that the latter may be placed in the former with ease of manipulation, and also in order that they may fall easily from the pockets, but the conformation of the inclined sides of the nut and the walls of the pocket causes the nut to be seated and held firmly in the pocket while being cut or grooved.- For adapting the machine for larger or smaller nuts the entire housing and presser foot mechanism may be shifted or adjusted by means of the bolts 43 and slots 42.0f the housing, and the cuttershaft is adjustable vertically in its slidable journal bearings in order to adapt the cutter for making shallow-or deeper slots or grooves in the crown of the nut. Revolving carriers with difi'erent sized pockets are of course used for difi'erent sized nuts, although the slots in the drums will vary but slightly in size. Other similar changes may be made without departing from the spirit of my invention or departing from the scope of my claims.

What I claim is 1. The combination with a revolvmg carrier havingpockets for nuts therein and a rotary cutter, of an adjustable housing, and

a flexibly supported presser foot in the hous-.

' cut by the cutter.

2. The combination with a revolving carrier and rotary cutter of a housing formed with guide flanges, a presser foot movable between said flanges and adapted to retain nuts in the carrier while being cut, perfoand pivoted, spring actuated guide bars in said lugs and pivoted to the presser foot.

3. The combination with a revolving nut carrier, of a shaft and cutter thereon and means for driving the shaft, vertically arranged slidable bearing blocks for said shaft, lower screw bars for lifting said blocks to adjust the position of the cutter, screw bars for clamping the blocks in adjusted position.

4. In a nut castellating machine a rotary carrier comprising a cylindrical drum having a series of spaced circumferential grooves, spaced rings fixed to the periphery of the drum registering with the grooves, and complementary notches on said rings forming. pockets of less depth than the grooves, and means co-acting with the grooves for ejecting nuts from the pockets.

-5. The combination in a nut castellating machine with a revolving carrier having grooves therein, spaced rings each having form pockets registering with said grooves, a cutter, means for reand upper taining the nuts in the pockets, and a pawl located in each groove of the carrier adapted to eject the nuts from the pockets.-

6. The combination with a cylindrical 5 drum of a series of flat rings fixed thereon and spaced apart to form coves, the two outer rings of said series ormed with angular notches on their inner edges, and the intermediate rings-having similar notches on both edges to form nut retaining pock- 10 ets, and means located in each of said grooves for ejecting nuts from the pockets. In testimon whereof I aifix m signature.
